A 1.1-acre (0.45 ha) leachate pond has been successfully covered with a removable, inflated geomembrane. The cover is kept inflated with a 1 horsepower (0.75 kW) fan supplying only 3-tenths of an inch of water column of pressure (0.01 psi, or 75 Pa). The maximum height along the center of the inflated geomembrane is controlled by steel cables. The geomembrane is anchored to a perimeter concrete block with a removable anchorage. An automatic backup generator and fan are installed in case of a power outage or mechanical breakdown. A geomembrane material was selected for the cover that would be appropriate for the performance conditions of exposure, stress, chaffing, and operational wear from repeated installations and removals. The selected material was a reinforced 30-mil (0.76 mm) flexible polypropylene. The material was selected for its strength, toughnes, durability, and ease of repair. The cover has performed well over two winters experiencing high winds, intense rain, snow, and freezing conditions. The cost of this installation has already been fully recovered by the avoided leachate treatment costs. The cover has been successfully removed and reinstalled.
